Abstract: A delay locked loop is provided to reduce a jitter of an inner delay locked loop generated in a delay line by performing a duty cycle compensation in a digital type delay locked loop. A multiplexing unit(120) selects and outputs one of a rising clock and a falling clock having an opposite phase according to a phase comparison signal. A first delay line unit(160) generates a first internal clock by delaying the output clock of the multiplexing unit(120) for a predetermined time according to the phase comparison signal. The first delay line unit(160) generates a second internal clock having an opposite phase to the first internal clock by delaying the first internal clock for a predetermined time. A delay line control unit(200) outputs an enable-signal of which activation is controlled according to a phase difference between the rising clock and the falling clock when the duty cycle compensation operation is entered. A second delay line control unit(170) controls the first and second internal clocks in a different timing according to the activation state of the enable-signal. The second delay line unit(170) outputs a first clock and a second clock having a different delay time difference by delaying for a predetermined time. A phase control unit(300) compares a phase of the first clock with a phase of the second clock and determines a weight value according to the comparison result.
